E. The battery assembly attaches to the cover assembly with quarter-turn fasteners. A support
assembly holds the housing assemblies and battery assembly together. It also has an insulator
assembly. The insulator assembly electrically connects the battery assembly and housing assembly.
The battery assembly has six C-size, nickel-cadmium cells welded together with nickel straps. A
fully charged battery assembly can energize an external emergency exit light for approximately 20
minutes.

F. The housing assembly contains the electrical components of the power supply. A connector on the
housing assembly connects the power supply to external control switches, emergency exit lights
and power sources. The housing assembly also has a terminal assembly to connect power to the
battery assembly.

2. Operation. (See Figure 2)

A. The power supply has components to prevent damage by voltage spikes. It also has components to
prevent power fluctuations from causing the power supply to operate incorrectly.

B. An external pilot’s switch controls the operation of the power supply. The power supply circuits
operate as follows:

(1) With the pilot’s switch in the ON position, the power supply operates as it does during a power
failure. The pilot’s switch can be set to ON to test the power supply.

(2) With the pilot’s switch in the ARMED position, current on the input charge line charges the
battery assembly. If a power failure occurs, the power supply automatically energizes an exit
light.

(3) With the pilot’s switch in the OFF position, the silicon-controlled rectifier (SCR1) goes off. This
causes the power supply to go off. This is done after a power failure to prepare the power
supply for normal operation.

C. On power supply P/N 60-1321-7, a flight attendant’s switch is used to operate the power supply.
When set to ON, the power supply energizes the exit light.

COMPONENT MAINTENANCE MANUAL
PART NUMBER 60-1321

D. Power supply ON function.

(1) With the pilot’s switch in the ON position, 28 Vdc is applied to the power supply ARM circuit
through connector (J1), pin 3. Power is removed from the CHARGE circuit on connector (J1),
pin 2.

(2) Power removed from connector (J1), pin 2, causes the junction of diode (CR7) and
resistors (R12 and R14) to go low. This applies a low to the inputs of integrated circuit (U1),
pins 1 and 2. The output of integrated circuit (U1), pin 3, goes high.

(3) The voltage on connector (J1), pin 3, is applied to the gate of silicon-controlled rectifier (SCR1).
This causes silicon-controlled rectifier (SCR1) to conduct. Battery current flows through silicon-
controlled rectifier (SCR1) and causes transistors (Q1 and Q2) to switch on.

(4) When transistors (Q1 and Q2) conduct, zener diode (CR4) applies regulated power (Vcc) to
integrated circuit (U1), pin 14. Current also flows through potentiometer (R15). This causes the
input of integrated circuit (U1), pin 9, to go high.

(5) With both inputs of integrated circuit (U1), pins 9 and 10, at a high level, the output of
integrated circuit (U1), pin 8, goes low. The inputs of integrated circuit (U1), pins 4 and 5, also
go low. The output of integrated circuit (U1), pin 6, then goes high.

(6) When the outputs of integrated circuit (U1), pins 3 and 6, both go high, transistor (Q3)
conducts. This causes transistors (Q4 and Q5) to switch on. Battery current flows through
transistor (Q5) and causes the emergency exit light to come ON.

E. Low voltage shutoff function.

(1) A circuit latches the power supply OFF when the battery voltage goes below a set shutoff level.
This causes the emergency exit light to go OFF. The latch circuit prevents battery damage
caused by cell reversal. This can occur when the battery cells discharge too much. The pilot’s
switch must be set to OFF and power must be applied to the input to release the latch circuit.

(2) Potentiometer (R15) sets the shutoff level. When the battery voltage drops to 5.2 to 5.6 Vdc,
potentiometer (R15) applies a low to integrated circuit (U1), pin 9.

(3) The output of integrated circuit (U1), pin 8, goes high. The inputs at integrated circuit (U1),
pins 4 and 5, also go high. This causes the output of integrated circuit (U1), pin 6, to go low.
This causes transistors (Q3, Q4 and Q5) to shut off. The emergency exit light goes OFF.

(4) Integrated circuit (U1) inverts the high signal at pin 8 at pins 12 and 13. The output of
integrated circuit (U1), pin 11, goes low. This latches the output of integrated circuit (U1), pin 8,
high. The circuit stays in this condition until the latch circuit is released.

F. Power supply ARMED function.

(1) With the pilot’s switch in the ARMED position, input power is applied to the power supply
through connector (J1), pins 2 and 3.

(2) On power supply P/N 60-1321-7, resistor (R20), capacitors (C6 and C7) and diodes (CR9
and CR10) make a half-wave rectifier. This circuit converts the 115-Vac input at connector (J1),
pin 2, to direct current. The rectifier circuit applies this dc voltage to blocking diode (CR1).

COMPONENT MAINTENANCE MANUAL
PART NUMBER 60-1321

(3) Current flows through blocking diode (CR1), current limiting-resistor (R1) and battery
assembly (BT1) to ground at connector (J1), pin 5. Battery assembly (BT1) charges
continuously until a power failure occurs.

(4) Power removed from connector (J1), pin 2, causes the junction of diode (CR7) and
resistors (R12 and R14) to go low. This applies a low to the inputs of integrated circuit (U1),
pins 1 and 2. The output of integrated circuit (U1), pin 3, goes high.

(5) The voltage on connector (J1), pin 3, goes to the gate of silicon-controlled rectifier (SCR1). This
causes silicon-controlled rectifier (SCR1) to conduct. Battery current flows through silicon-
controlled rectifier (SCR1) and causes transistors (Q1 and Q2) to turn on.

(6) When transistors (Q1 and Q2) conduct, zener diode (CR4) applies regulated power (Vcc) to
integrated circuit (U1), pin 14. Current also flows through potentiometer (R15). This causes the
output of integrated circuit (U1), pin 9, to go high.

(7) With both inputs of integrated circuit (U1), pins 9 and 10, at a high level, the output of
integrated circuit (U1), pin 8, goes low. The inputs of integrated circuit (U1), pins 4 and 5, also
go low. The output of integrated circuit (U1), pin 6, then goes high.

(8) When the outputs of integrated circuit (U1), pins 3 and 6, both go high, transistor (Q3)
conducts. This causes transistors (Q4 and Q5) to switch on. Battery current flows through
transistor (Q5) and causes the emergency exit light to turn ON.

G. Power supply OFF function.

(1) With the pilot’s switch in the OFF position, input power is applied to connector (J1), pins 2
and 4.

(2) On power supply P/N 60-1321-7, resistor (R20), capacitors (C6 and C7) and diodes (CR9
and CR10) make a half-wave rectifier. This circuit converts the 115-Vac input at connector (J1),
pin 2, to direct current.

(3) Current flows through diode (CR6). This causes the junction of resistors (R12 and R14) and
diode (CR7) to go high. The potentials on both sides of diode (CR7) balance. The causes the
output of integrated circuit (U1), pin 3, to go low. Transistors (Q3, Q4 and Q5) switch off. This
stops the flow of current through transistor (Q5) and to the emergency exit light.

(4) The voltage from connector (J1), pin 4, back-biases silicon-controlled rectifier (SCR1). This
stops the flow of current from battery assembly (BT1) through silicon-controlled
rectifier (SCR1). Transistors (Q1 and Q2) switch off. This removes the regulated power (Vcc)
from integrated circuit (U1).

H. Flight attendant’s switch function (power supply P/N 60-1321-7 only).

(1) When the flight attendant’s switch is set to ON, ground potential is removed from the junctions
of diodes (CR11 and CR12). This allows current from the charge circuit to flow to the base of
transistor (Q6). This causes transistor (Q6) to conduct. This causes transistors (Q7 and Q5) to
switch on. Battery current flows through transistor (Q5) and causes the emergency exit light to
come ON.

(2) When the flight attendant’s switch is set to NORMAL, ground potential is applied to the
junctions of diodes (CR11 and CR12). This switches transistor (Q6) off. Transistors (Q7
and Q5) then switch off. This stops the flow of current through transistor (Q5) and to the
emergency exit light.

5. Storage.

NOTE: Refer to IPL Figure 1 for an illustration. Numbers in parentheses ( ) refer to item numbers
on the illustration.

A. General conditions for battery storage.

(1) Subjection to extreme variations in temperature during storage or shipment will cause some
loss of charge due to “self-discharge” characteristics of nickel-cadmium cells.

(2) Storage temperatures should not go below -40 °F (-40 °C) or more than 165 °F (74 °C) to
prevent damage to cell structures. At storage temperatures above 100 °F (37.78 °C), self-
discharge will increase considerably compared to self-discharge at 68 °F (20 °C). Cold storage
at 32 °F (0 °C) offers definite improvement of charge retention and is recommended when
practical.

(3) Self-discharge of cells may be minimized by storage at 32 °F (0 °C) with a loss of


approximately 10% of available capacity after 50 days storage. Storage at 68 °F (20 °C) will
produce a 50% loss in available power after a storage period of 50 days. Fully charged battery
assemblies stored at 32 °F (0 °C) for up to 50 days may normally be placed in service without
further charging. Fully charged battery assemblies stored at no more than 68 °F (20 °C) for up
to 7 days may normally be placed in service without further charging.

B. Storage for line maintenance.

(1) Power supplies or battery assemblies in a fully charged state may be stored under the following
controlled conditions and placed into immediate service without additional charging:

(a) Storage at 68 °F (20 °C) for a period of 7 days or less.

(b) Storage at 32 °F (0 °C) for a period of 50 days or less.

(c) Trickle-charge storage for up to six months.

C. Storage for other than line maintenance.

(1) Battery assemblies may be stored in the power supply or removed from the power supply.

(2) Battery assemblies may be stored at -4 °F (-20 °C) to 122 °F (50 °C) for an indefinite storage
period.

D. Charging of battery assembly (BT1) (275) after storage.

(1) Power supply and battery assembly (BT1) (275) removed from storage should be inspected for
visible damage. Battery terminals and contacts should be cleaned prior to charging. A white
deposit present on battery terminals and/or contacts is not abnormal and may be removed with
a clean cloth dampened with warm water.

(2) Apply a constant DC current of 265 mA to battery assembly (BT1) (275) for 16 to 20 hours.

33-50-42 Page 703


Jul 1/00
GRIMES AEROSPACE COMPANY
COMPONENT MAINTENANCE MANUAL
PART NUMBER 60-1321

(3) At completion of the charging operation, and with the power supply still on charge, battery
assembly (BT1) (275) shall measure a minimum of 8.4 Vdc. If less than 8.4 Vdc is measured,
continue the charging operation for an additional 4 hours.

(4) If the battery assembly (BT1) (275) still does not measure a minimum of 8.4 Vdc, replace
battery assembly (BT1) (275).

E. Trickle-charge storage.

(1) Fully charged battery assembly (BT1) (275) may be stored under trickle-charge condition for up
to six months and be placed into immediate service without additional charging.

(2) Storage temperature must not exceed 100 °F (38 °C).

(3) A battery assembly (BT1) (275) stored under trickle-charge condition in excess of six months
should not be immediately placed in service. Instead, battery assembly (BT1) (275) should be
removed and discharged under a 2-amp load down to 0.9 Vdc per cell and then charged for 24
hours.

NOTE: Battery cells should be individually loaded and measured to detect shorted or
reverse-charged cells.

(4) To trickle-charge battery assembly (BT1) (275), apply a constant current of 100 mA dc.

F. Pack the power supply as follows:

(1) Wipe the power supply with a clean cloth to remove dirt, dust and foreign material.

(2) Preserve the power supply in accordance with MIL-P-116, Method 1-A-8.

(3) Wrap the power supply in wrapping material and place in plastic bag.

(4) Place cushion and dunnage material, desiccant and the power supply in unit container, then
seal with masking tape.

(5) Mark outside of unit container in accordance with MIL-STD-129. Also include overhaul date and
location.

ILLUSTRATED PARTS LIST

1. General Information.

A. The Illustrated Parts List (IPL) provides a breakdown of assemblies, subassemblies and detail parts
of the power supply. All parts are listed, except for parts which lose their identities by being
permanently fastened to other parts or are part of an assembly not subject to disassembly.

B. Bulk materials such as backshells, contacts, ring terminals, safety or electrical wires, strain reliefs,
tape and Ty-Raps and consumable materials such as adhesives, sealants, lubricants, solder, paints
and primers are not included in the detailed parts lists. These materials are identified in the
materials list at the beginning of each section.

C. To find a part number when the part number is unknown, locate the part on the illustration and note
the item number. Locate the item number on the detailed parts list. The part number will be shown
on the same line. In some instances there are gaps in item number sequence and the item numbers
are not continuously sequential.

2. Explanation of Columns, Terms and Symbols in the Illustrated Parts List (IPL).

A. FIG. & ITEM NO. column: The figure and item numbers key the detailed parts list to the applicable
illustration. The first number represents the figure number of the illustration. The item number
corresponds to an item number on the illustration.

(1) An item number not on the illustration is identified by a dash (-) preceding the item number.
This can indicate the following:

(a) When two or more visually alike parts are listed in sequence, only the first part is
illustrated. The illustration, however, is applicable to both parts.

(b) When detail parts of an assembly or installation are separately illustrated, the resulting
assembly may be illustrated as an assembly by bracketing the detail parts and identifying
the bracket as the assembly. If brackets are not used, the detail parts are illustrated, but
the assembly is not.

(2) An item number followed by an alphabetical character such as A, B, C, etc., indicates the part
listed is similar to the same item number without the alphabetical character. The difference
could be each part is used for a different next higher assembly (NHA) or is an equivalent part.
This will be noted in the NOMENCLATURE or EFF CODE columns.

B. PART NUMBER column: This column contains the original manufacturer’s part number of the
assembly, subassembly or detail part listed. Part numbers in this IPL are those of Grimes
Aerospace Company, Urbana, Ohio (V72914) or are standard parts unless a Commercial and
Government Entity (CAGE) code appears in the NOMENCLATURE column. Refer to paragraph 4
for details. The following phrases may be used in this column:

„ “ORDER NHA” is used when no part number exists for the part listed or when it is preferable to
order an assembly rather than detail parts. ORDER NHA items which have no part numbers
are not procurable and should not be ordered. The next higher assembly, however, is
procurable and may be ordered.

33-50-42 Page 1001


Jul 1/00
GRIMES AEROSPACE COMPANY
COMPONENT MAINTENANCE MANUAL
PART NUMBER 60-1321

„ “NONPROC” followed by an assigned number (for example NONPROC123) is used when no


part number exists for the assembly. NONPROC assemblies are not procurable and may not
be ordered. However, the detail parts of the assembly are procurable and may be ordered,
unless otherwise specified.

„ “REF” followed by an assigned number (for example REF001) is used when the part number is
more than fifteen digits. The original part number with more than fifteen digits is listed in the
NOMENCLATURE column and is the part number to be used when ordering the part.

C. AIRLINE STOCK NO. column: This column is reserved for airline part numbers and accommodates
eleven numbers.

D. NOMENCLATURE column: This column identifies the parts being listed by noun name followed by
modifiers when applicable. This includes assemblies which are not broken down within the IPL.
Assemblies which are broken down within the IPL will be listed in plain English. This column also
provides the following information:

(1) The relationship of each listed item to its next higher assembly (NHA) is shown by an indenture
code. Each listed item is placed in the NOMENCLATURE column one indenture (one dot) to
the right of the assembly to which it belongs. Items at equal indentures are all components of a
single assembly or subassembly. An example of the indenture code system is shown below:

1 2 3 4 5 6 7

. Attaching Parts for Assembly
. . Detail Parts for Assembly
. . . Subassembly
. . . Attaching Parts for Subassembly
. . . . Detail Parts for Subassembly
. . . . . Sub-Subassembly
. . . . . Attaching Parts for Sub-Subassembly
. . . . . . Detail Parts for Sub-Subassembly

(2) Symbols used, with the exception of effectivity and CAGE codes, are as follows:

(ATTACHING PARTS) Designates start of each group of attaching parts.


-------*------- Designates end of each group of attaching parts.

(3) The following phrases may be used in this column:

„ “DELETED” identifies a part no longer used.

„ “SUPSD” identifies a part no longer authorized for use; quantities will be listed as “NP.”
Example: (SUPSD BY ITEM XXX).

„ “SUPSDS” identifies the newer part to be used. Example: (SUPSDS ITEM XXX).

„ “REPLACES” or “REPLACES ITEM XXX” identifies this part is newer and therefore more
desirable than the “REPLACED” part. However, either may be used.

33-50-42 Page 1002


Jul 1/00
GRIMES AEROSPACE COMPANY
COMPONENT MAINTENANCE MANUAL
PART NUMBER 60-1321

„ “REPLACED” or “REPL BY ITEM XXX” identifies this part is older and therefore less
desirable than the “REPLACES” part. However, either may be used.

„ “ALTN PART FOR ITEM XXX” identifies this part as an alternative. However, either part
may be used and neither is more desirable than the other.

„ “TPN” precedes a True Part Number with all dashes, slashes, spaces and/or symbols
assigned by the original manufacturer of the part. This is the part number to be used
when ordering the part.

E. EFF CODE column: This column establishes part relationship with assemblies, which are essentially
the same, but have minor variations. These assemblies are the end items on the detailed parts list
and are assigned reference letters such as A, B, C, D, etc. Subassemblies or detail parts, which are
not common to all configurations, but are associated with one or more of the coded end items, carry
the letter or letters assigned to the end item(s) with which they are associated. If a part is common
to all end items, the EFF CODE column is blank.

F. UNITS PER ASSY column: This column shows the quantity of each item required for the next higher
subassembly, assembly or installation outline. The quantity shown for attaching parts is the total
number required for the related part, subassembly or assembly and, therefore, may not be the total
quantity used for the end item of the detailed parts list. The following letters may be used in this
column:

„ “AR” indicates “as required” and refers to variable quantity items such as shims, spacers or
similar items.

„ “RF” indicates "reference" and refers to items and their quantities which are listed elsewhere
and are provided here as a reference only.

„ "NP" indicates "nonprocurable" and refers to items which are not procurable and may not be
ordered.

3. Abbreviations. Standard abbreviations used in the IPL agree with MIL-STD-12, except as noted below:

Abbreviation Definition

None

4. Commercial and Government Entity (CAGE) Codes.

A. CAGE codes, preceded by the capital letter "V" (V12345), are used to identify the original
manufacturer of non-Grimes Aerospace Company (V72914) components. CAGE codes are listed in
the NOMENCLATURE column, except for the Government codes below, which are not listed:

V96906 Military Standard (prefix MS)


V88044 Army/Navy Standard (prefix AN)
